Best cad software for linux
AI summary
FreeCAD is the best default for 3D parametric modeling; choose BricsCAD when professional commercial support and DWG compatibility matter more. For users seeking browser-based collaboration similar to mainstream proprietary tools, Onshape provides a strong cloud-native alternative. Alternatively, LibreCAD or QCAD serve best for lightweight 2D drafting, while OpenSCAD and CadQuery suit programmers preferring code-driven designs. Specialized options like SolveSpace and VariCAD fulfill rapid constraint sketching and mechanical computations respectively, and Siemens NX handles heavy enterprise environments.

If you mean serious CAD on Linux, my top pick is FreeCAD.
Best Linux CAD options
| Software | Best for | Linux | Cost |
|---|---|---|---|
| FreeCAD | Mechanical/parametric 3D CAD, 3D printing, CNC | Native | Free/open source |
| BricsCAD | Professional 2D/3D CAD, AutoCAD-like workflows | Native | Paid |
| Onshape | Polished modern CAD, collaboration | Browser | Free/paid |
| LibreCAD | Simple 2D drafting | Native | Free/open source |
| OpenSCAD | Programmatic/parametric models | Native | Free/open source |
🥇 FreeCAD — best overall
FreeCAD is where I'd start for most Linux users. It has parametric solid modeling, constraint-based sketches, assemblies, technical drawings, CAM/CNC, FEM, BIM, and broad format support including STEP, IGES, STL and DXF. www.freecad.org
The big advantage is that it's genuinely native Linux software and doesn't require a cloud account or Windows VM. Its 1.x releases have also substantially improved the experience, including a built-in Assembly workbench. www.freecad.org
Downside: the workflow is less polished than Fusion 360/SolidWorks, and there is a learning curve. Recent Linux CAD discussions still frequently praise FreeCAD while criticizing its usability and occasional stability issues. www.reddit.com
🥈 BricsCAD — best professional AutoCAD alternative
If your work is primarily 2D drafting, DWG files, architectural drawings, or AutoCAD-style CAD, I'd seriously consider BricsCAD instead. Current BricsCAD supports Ubuntu, Fedora and openSUSE on x86-64 Linux. help.bricsys.com
It's the better choice if DWG compatibility and professional 2D drafting matter more than having an open-source application.
🥉 Onshape — best user experience
Onshape is worth considering if you're okay with CAD running in a web browser. It's particularly attractive if you want something closer to the polished Fusion 360/SolidWorks experience. Community feedback in 2026 has been quite positive about its usability on Linux. www.reddit.com
The tradeoff is that your designs live in the cloud, and the free tier has important limitations.
My recommendation
- 3D printing / mechanical parts: FreeCAD
- Engineering / serious parametric modeling: FreeCAD, then consider Onshape
- AutoCAD/DWG replacement: BricsCAD
- Simple 2D drawings: LibreCAD
- CAD controlled by code: OpenSCAD
- Want the closest thing to Fusion 360's UX: Onshape
If you tell me what you're designing (3D printing, woodworking, mechanical engineering, architecture, CNC, electronics enclosures, etc.), I can narrow it down to the best 1–2 choices for your specific workflow.
